| 英文摘要 | A large number of fluorinated chemicals have been synthesized and used worldwide because of their unique properties. However, because of the strong C-F bond, fluorinated chemicals are not decomposed in nature. Herein, the activity of gallium oxide toward the degradation of trifluoromethyl benzoic acid in aqueous media was examined under UVC radiation by using a low-pressure mercury lamp as the light source. The degradation process was monitored by HPLC, UV-Vis spectroscopy and TOF-MS techniques, which permitted some intermediates to be identified. The defluorination efficiency was greater under a nitrogen atmosphere than in air, with the para-isomer (4-(trifluoromethyl)benzoic acid) being more prone to degradation (ca. 90%). The degradation mechanism was proposed on the basis of the theoretical calculation on the electron density and the intermediate analysis. |
